ShadersManager

public ShadersManager(com.jogamp.opengl.GLContext glContext,
 com.jogamp.opengl.glu.GLU glu)

Setups buffers and textures. To be used in the initialisation phase of the OpenGl context.

Parameters:

glContext - An OpenGL context. Must not be null, must be at least GL2

glu - An OpenGL utilities. Must not be null

Throws:

com.jogamp.opengl.GLException - if the shaders' initiation fails

Method Details

renderObjects

public void renderObjects(Collection<Drawable> drawables,
 int viewPortWidth,
 int viewPortHeight,
 javax.vecmath.Vector4f lightPosition)

Puts drawable objects through pipeline which enables to render fog simulation and contours.

Parameters:

drawables - objects to be rendered

viewPortWidth - current width of the viewport

viewPortHeight - current height of the viewport

lightPosition - the position of the scene's light in homogenous object coordinates.

setFogVersion

public void setFogVersion(int fogVersion)

Setter for fog rendering type

Parameters:

fogVersion - Enumerated type of fog

setUseContours

public void setUseContours(boolean useContours)

Setter for turning contours on and off

Parameters:

useContours - boolean to set the contours to

setUseGlyphs

public void setUseGlyphs(boolean useGlyphs)

Setter for turning glyphs on and off

Parameters:

useGlyphs - boolean to set the glyphs to
